SPLCIFICATION forming part ofvLetters Patent No. 292,550, dated January 29, 1884.

' Application filed May 3,1583. (N rimasi.)

To all whom it maywncern:

Beitknown that I, JOHN S. FAIRLY, of Charleston, in the county of Charleston and State of South Carolina, have invented a new and Improved 'Separator and Conveyer, of which the following is a full, clear, and exact description.

My improved device is designed more especially for the separation of the kernels of cotton-seed from the hulls after passing through the huller, but may b'e used for the separation of other materials.

The invention consists in a screw-conveyer provided with nights in sections, armed at their outer edges with a nexible or pliable material, and combined with a perforated trough or box, as hereinafter describedand claimed. .A Y

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in ,both the figures.

Figure l is a side elevation ofthe separator, and Fig. 2 is a transverse section of the same on line x x.;

A is the shaft, and B B the nights, of the conveyer. C is thev box or trough. that may be made of sheet metal or other suitable material, and is formed in the bottom, as shown in Fig. 2, with apertures a, of a size to allow the kernels to pass through freely. The nights B may be of wood or metal. Instead of being continuous,they are insections, or cut out to within a short distance of the shaft to which the screw is attached. The effect of this arrangement is that the nights carry the material over or partly over the screw without moving it continuously forward, and thus separate the heavier kernels from the light hulls,

der to keep the perforations free, the nights should run close to the bottom, and to prevent rapid wear they are -fitted-on their edges with strips d, of leather or other suitable material of nexible character.

This device acts effectively for the purpose, and can be run with comparatively little pow er. It is unich less expensive and lmore durable than separators of usual construction. In its operation the 'agitation of the materials by the nights causes the separation. The kernels, being the heavier, settle to the bottom and pass" out through theperforations, which are kept open by the soft or pliable armor on the ends of the hinges into a suitable receptacle. The'hulls are moved forward in the box until the end of the box is reached,"where they are discharged.

The apparatus may be of any suitable length and the screw of any desired diameter.

Having thus described'my invention, what I claim as new, and desire to secure by Letters l
